MEASURING DEVICE.

To 'all t may concern.'

'B e it known that I, CHARLES S. LEWIS, a citizen of the United States, residing at St. Louis, Missouri, have 'invented a certain new and useful `Improvement in Measuring Devices, Aof which the following isa full, clear, and exact description, such as will enable others 'skilledin 'the art to which it ap'per-l z example, :as the top portion of the neck of tains to make and use the same.

'1`his invention relates Ato devices that are: used for measuring liquid, semi-liquid, andgranular or powdered materials. One lobject of my invention is to provide it will permit only a predetermined quantity of materialto be discharged when the container is tiltedor arranged in suchV a position that the material therein can escape.

Another Objectis to provide adevice of the character above-mentioned that will automatically measure a predetermined quantity of material -.whenever the container is tilted or actuated to discharge the material that was previously measured. c

Another object is to provide a device of the character described which 'also acts as a cap or closure for the receptacle or container o n which it is used.

And still another object is to provide an inexpensive measuring device that com prises only a few substantial parts which can be cleaned easily.

@ther objects and desirable features of ny invention will be vhereinafter pointedl out.

Figure 1 of the drawings -is a vertical sectional view of a measuring device constructed in accordance with my invention;

and Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1.- Referring to the drawings wh'ch illustrate the preferred form of my invention, A designates ya container`which may be a bottle, a can, a cask, or,""m fact, any suitable kind of receptacle provided with a dis.

l Achargie openingfor permitting the materialin same'to escape.

My improved measuring device consists of. a casing or shell 1 whose interior is i vided into two chambers -B and C which are separated Irom each other by a horizontally -Specication of Le'tters Patent. lapplicationined .rune-4, 1912. -serialwa'vorsm Patented July 1, 1913.

disposed partition' 2, the cubical contents o'f the Vupper chamber B being greater than the cubical contents of the lower chamber C. The device can be applied to the receptacle on which it is used in various Ways. It can be provided on its 'underside with a socket or recess whose annular wall 3 surrounds a vertical flange on thereceptacle, such, for

a bottle; it can be provided with a tubularshaped portion 4 that projects into the discharge opening of the receptacle; or it can be provided with both of said parts or members as herein shown. The annular wall 3 ofthe socket in the lower end of the device,

or the tubular-shaped part 4 on the device, or both of said parts can be so designed that theyfit the coperatinguportion ofthe re.

ceptacle snugly, or ann ar packing members 5 can be arranged between the device and the coperating part of`the receptacle on which the device is mounted.

A port or opening is formed in the 'partitio n 2 preferably at a pointin alinem'ent with the discharge openingin 'the receptacle A so as to permit the material to lowwfrom said receptacle into the receiving chamber B. In the preferred form of my invention as lherein shown, the tubular-shaped portion 4 of the device establishes communication between the receptacle and chamber B, and said tubular-shaped portion is provided with an extension 4" that-projects into/ 'the chamber B, thus 'forming an open-'ended passageway leading from the receptacle A and the receiving chamber B'. n

` The material that enters the chamber B escapes into the measuring chamber 'C through one or more ports in the partition 2, the device herein shown having an elongated slot 6 formed in the partition 2, as

shown clearly in Fi 2. The 4dischaig'e opening through whic the measured material escapes from the chamber C preferably consists of a portin the partition 2 that communicates with a4 duct 7 formed in a spout 8 that rejects laterally from the casing 1 ofthe evice, as shown in Fig. 2. It is not essential, however, that the 'device bfc 'rovided with a spout for, if desired, the uct through which the material escapes fromthe measuring chamber C steld nate flush with the outer surface of the casing 6 is formed in the extension 4 of theV tubular-shaped member 4 at a point just above. lthe upper side ofthe partition 2 so as to permit air to enter the receptacle or container A when the material is flowing out of same and also to form an overflow opening that permits the surplus material in the receiving chamber B to lHow back into the receptacle A, as hereinafter described. Airis admitted to the upper chamber B through an air port or opening 10 formed in the dome-shaped top of the caslng 1. d

As shown in the drawings, the overiow port 9, the opening 6 in the partition 2, and the air port 10 in the casing are preferably formed at one side of the device and diametrically opposite the discharge spout 8. Consequently, when the .container A is tiltedor inclined in such amanner that the measuring device moves in the direction indicated by the arrow a: in Fig. 1, the spout 8 being located on the under side of the device, some of the material in the container will flow through the open-ended tubularshaped member 4 directly into the receiving chamber B. When the container A is restored to its former upright position the material that has entered the chamber B will ow from said chamber through the opening 6 in the partition into the'measuring .chamber C, the excess material or material which cannot enter the chamber C, escaping from the receiving chamberB back into the container, through the overflow openmg 9 in the extension of the tubular-shaped member 4. The chamber C 'no w contains a predetermined quantity of material, and when the container` is again tilted or actuated in the manner pr'eviou'sly described, tliie material in the-chamber C willlescape through the discharge duct 7' in the spout of the device. At thesame time, namely, when A the measured materialyis being discharged,

-the material in the-container A is flowing into the upper chamber'B through the tubular-shaped member 4, thus causing the chamber B to be villed automatically at the time the chamber C is being emptied. Y

From the foregoing it will be seen that each time the container or receptacle A is tilted or moved into a certainposition a predetermined quantity of material is discharged from the device, and when the conchamber Bh. cover the overflow' tainer is restored to its upright position the material which is next to be discharged is measured accurately. It is immaterial whether the container is merely tilted part` wa over orcom letely inverted for when cient has, entered the upper v v l rt9 and the irmlat Portillo., fhew 0 .thematerial from the container will be cut oif automatically owing to the fact that no air can enter the receptacle, the ports 9 and 10 thus l rial that can be cast or molded. I prefer to form the device in two parts from material that can be cast or molded, thelower part comprising the center portion of thepartition 2, the tubular-shaped member 4 and its extension, the annular wall 3 of the socket on the under side of the device, and the bottom wall 11 of the measuring chamber C, all integrally connected together. The upper part of the -device comprises the casing or shell 1 having a dome-shaped top and side walls which terminate, and preferably bear upon the top face'of the plate portion 11 of thc bottom part, the discharge spout 8 being preferably formed integral with the casing l and the casing being provided 'on its inner side with an annular ange that forms part of the horizontal partition 2 which separates the chambers B and C, the coperating partition portions on the top and bottom parts of the device being screwed together at 2, as shown in Fig. 1. A device of the construction above-described' comprises only two substantial parts which are inexpensive to manufacture and it can be taken apart easilyfor cleansing by simply unscrewing the two parts at the oint where the coperating partition portlons of same are connected'4 together. If desired, packing can be arranged between the lower edge of the casing 1 and the top face of the bottom plate ortion 11 on which the edge of the casing rears, but this is not necessary if the device is form'ed of metal, for there will-be suiicient resiliency in the metal to insure a tight joint.

for the bottle and permits onl a predeteri mined quantit of material to e discharged whenever the ttle-is tilted or moved into a osition to discharge its contents.l Y
